Creation Operations

Creation operations in SQLite involve adding new records to a database table. These operations allow you to populate your tables with data. Let's explore how insertion operations work within the context of database creation.

Inserting a Record

This code snippet uses the SQL INSERT INTO statement to add a new record to the "users" table, inserting values for the "username" and "email" fields. The data is passed as a tuple, and the query is executed with the execute() method to insert the values.

python

Be careful because this code considers working on an already existing table. If you don't have a users table in your database, then you need to create one.

To avoid the error, you need to create a table in the database with the name users and fields username and email. Only after that can you add records to this table.

  1. Write an SQL query to insert a new record into the articles table. The query should insert values into the title, content, and author columns. Store the query in the variable insert_query.

  2. Use the cursor method to execute the SQL query with the data stored in the article_data variable.
